Abstract (en)
[origin: US5279743A] A process for the separation of a mixture of zinc and manganese oxides by adding the mixture to a chloric acid solution whereby the chloric acid solution oxidizes solid manganese oxide to solid manganese dioxide and causes the zinc oxide to dissolve into soluble zinc ions. The solid manganese dioxide is then separated from the chloric acid solution containing zinc ions.
